ANALYSIS ON THE RELASHIONSHIP BETWEEN PROPERTIES OF URBAN BLOCK AND WIND PATH IN THE STREET CANYON FOR THE USE OF THE WIND AS THE CLIMATE RESOURCES

Abstract

To promote ventilation in the street canyon is one of the effective heat island measures. The analysis on the relationship between properties of urban block and wind environment in the street canyon is required. In this study, relationship between wind environment in the street canyon and the direction of street, the width of street and the building height beside street is studied by CFD simulation result and observation result. Wind velocity ratio, which is calculated in street wind velocity by upper wind velocity, is used for the index of wind environment in the street canyon.
